The Serpent 13mm rear shock spring is supplied in red and rated at 2lbs, serving as a direct replacement spring for rear shock assemblies. It is sold as a single spring to modify rear suspension behaviour rather than as a complete shock unit.
Fit the spring over the shock shaft or into the retainer after disassembly, then reassemble the shock and check preload and travel before running the car.
Pair spring selection with the proper shock oil viscosity and spring preload to maintain consistent handling across sessions. This component is intended solely for RC model vehicles and setup trials on track or off-road.
